DETAILED DESCRIPTION

FIG. 1 illustrates example communication of a user device 122 with terminal devices in two example spaces (spaces 102 and 104). A space is one or more physical areas inside of, outside of, or both inside and outside of a home, office building, or other structure. A given physical area of a space can be adjacent to one or more other physical areas of the space. For instance, if a space comprises two physical areas, each being on a different floor or level of a building, the floors or levels can be adjacent (e.g., floors 1 and 2) or non-adjacent (e.g., floors 1 and 5). As shown in FIG. 1, space 102 comprises the physical area of the living room of a home and space 104 comprises the physical area of the bedroom of the home. Spaces can be different shapes and sizes and, in some implementations, may overlap with each other. Spaces do not need to be delineated by walls, floors or other kinds of barriers. For example, the spaces 102 and 104 could comprise a single space or a given room in a home could comprise multiple spaces.

A space can contain one or more terminal devices. For example, space 102 contains terminal devices 106, 108, 110 and 112, and space 104 contains terminal devices 114, 116, 118 and 120. A terminal device is a data processing apparatus or other device that is configured to monitor the operation or state of a piece of equipment or of an environment and, in some implementations, control the operation of the equipment. For example, a piece of equipment can be a light, an appliance (e.g., an oven, a slow cooker, a bread maker, a curling iron, and so on), a thermostat, or heating ventilation and air conditioning equipment. By way of illustration, a terminal device can turn a lamp on or off, or dim the lamp's light. Or a terminal device can monitor whether a window is open or closed, for instance. In some implementations, a terminal device includes a microprocessor, one or more radio transceivers, memory, and sensors for monitoring and/or controlling a piece of equipment. Other types of terminal devices are possible. (Terminal devices are described further in reference to FIG. 4.) Terminal devices can use their radio transceiver(s) to communicate wirelessly with user devices (e.g., user device 122), other terminal devices, and equipment that is configured to communicate wirelessly (e.g., a wireless-enabled thermostat or a wireless network hub).

A terminal device can be integrated into a piece of equipment (e.g., a wall socket, a light switch, a window, a door, an appliance) or can be separate device that is coupled physically or wirelessly to a piece of equipment. FIG. 3 illustrates the exterior of an example terminal device that is in the form of a smart plug 300. The smart plug 300 includes a power connector 302 for connecting the smart plug 300 to a power outlet such as a wall socket. The smart plug 300 also includes a power receptacle 304 which accepts the power connector of a piece of equipment. The top, bottom, or side of the smart plug 300 can optionally include a button 306 which, in some implementations, enables or disables the piece of equipment connected to the power receptacle 304 when pressed. The interior of the smart plug 300 includes processors and circuitry for monitoring and controlling equipment that is connected to the power receptacle, and will be described further below with reference to FIG. 4.

Referring again to FIG. 1, and by way of illustration, in space 102 terminal device 106 is coupled to a television (not shown), terminal device 108 is coupled to a ceiling light (not shown), and terminal devices 110 and 112 are coupled to electrically powered speakers (not shown). In space 104, terminal device 116 monitors whether a window 116 a is open or closed, terminal device 118 is coupled to a bedside lamp (not shown), terminal device 120 is coupled to a stereo (not shown), and terminal device 114 is coupled to another lamp (not shown). User devices can wirelessly transmit commands (“command packets”) to terminal devices to control the respective equipment that is coupled to the terminal devices. For example, the user device 122 can transmit a command packet to terminal device 106 to turn the television on or off. Similarly, the user device 122 can send a command packet to terminal device 108 that instructs the terminal device 108 to dim the ceiling light that the terminal device 108 is coupled to. The term “packet” as used herein refers to information that is transmitted as one or more basic transfer units (or other units) of a communication protocol.

A user device (e.g., the user device 122) is a data processing apparatus such as a smart phone, a tablet computer, a portable computer, or a wearable computing device such as a wristwatch or eye glasses, for example. Other types of user devices are possible. In various implementations, the user device 122 presents a graphical user interface (GUI) that shows equipment coupled to terminal devices in the space the user device is currently located in (e.g., the living room). Alternatively, the GUI can show equipment in a space or spaces of a user's choosing.

The GUI allows a user to monitor state and/or energy usage of equipment coupled to terminal devices and to control the equipment. For example, the GUI shows the current state of the television (on), the current state of the light (on) and the current state of the stereo speakers (off). By way of further example, if a user selected GUI control 122 a for controlling the right speaker, the user device 122 would send a command packet to the terminal device 112 in response to the selection to enable (or disable) the speaker coupled to the terminal device 112. User interaction with the GUI can be through touch or keyboard input, voice input, or motion input (e.g., the user moves the user device 122 in a predetermined pattern). Other user interaction is possible. The GUI will be discussed further below in regards to FIGS. 6A-6E.

Terminal devices make their presence known to user devices by wirelessly broadcasting a so-called advertisement packet at various times or when prompted by a broadcast message sent by a user device. In some implementations, the advertisement packet contains the transmit power of the terminal device, a terminal device identifier, status information, and a network identifier. The advertisement packet can contain fewer or additional pieces of information, however. The transmit power is a measure of the transmission power used by the transmitting radio of the terminal device. The terminal device identifier is a unique identifier for every terminal device and can be assigned to the terminal device when the terminal device is manufactured, for example. Alternatively, the terminal device identifier can be assigned to the terminal device when the terminal device is initialized (see FIG. 5). The status information indicates additional data that is available either in the advertisement packet itself or that can be requested from the terminal device. Such information can include, for example, the status of the equipment (e.g., on or off), the current dim level if the equipment is a dimmable light, and information detailing the energy usage of the equipment over time. The network identifier is assigned to the terminal device during initialization of the terminal device and indicates which user or entity initialized the terminal device. Initialization of terminal devices is described further below with reference to FIG. 5.

As discussed above, the user device 122 needs to determine which space the user device 122 is currently located in. In various implementations the user device 122 maintains a mapping between the terminal device identifiers and identifiers of the respective spaces assigned to the terminal devices. (Terminal devices are assigned to spaces during the initialization process as described in reference to FIG. 5.) If the user device 122 only receives advertisement packets from terminal devices that are assigned to the same space (e.g., the living room), then the user device 122 determines that it is currently located in that space. However, if the user device 122 receives advertisement packets from terminal devices in two or more spaces the user device 122 can determine which space it is currently located in as follows.

In some implementations, the user device 122 determines which space it is currently located in based on analyzing received signal strength indicators (RSSIs) of each terminal device the user device 122 receives advertisement packets from. The RSSI is a measurement of the power present in a received radio signal and can be calculated by the user device 122′s radio. (Alternatively, the RSSI value is a measure of the power present in the radio signal transmitted by the user device 122 as measured by radio of a respective terminal device. In this scenario the terminal device provides the RSSI value in the advertisement packet to the user device 122, for example.) The RSSI value can be a power ratio in decibels (dBm) of the measured power referenced to one milliwatt (mW). For example, the RSSI can be calculated as follows:

RSSI=−(10 n log₁₀ d+A)

where n is a signal propagation constant or exponent, d is a distance from the sender and A is the received signal strength at a predefined distance. Other ways of calculating RSSI are possible.

In some implementations, each RSSI value is converted to an estimation of the distance between the user device 122 and the respective terminal device. The distance can be calculated by the communication protocol used by the user device 122 and the terminal devices, for example. In other implementations, each RSSI value is not converted to an estimation of distance since the distance estimation can be inaccurate due to interference. The user device 122 averages the distances (or RSSI values) of terminal devices in the same space and then determines that the space the user device 122 is currently located in is the space having the shortest average distance (or smallest average RSSI value).

By way of illustration, the user device 122 receives advertisement packets from terminal devices that are in range of the user device 122. For example, space 102 terminal devices 106, 108, 110, 112 and space 104 terminal devices 114 and 116 are in range of the user device 122. The user device 122 calculates the average distance (or RSSI value) for space 102 based on the RSSI values for terminal devices 106, 108, 110, 112, and calculates the average distance (or RSSI value) for space 104 based on the RSSI values for terminal devices 114 and 116. If the average distance (or RSSI value) for space 102 is less than that for space 104, then the user device 122 is currently located in space 102. Otherwise, the user device 122 is currently located space 104. If the average distances (or RSSI values) of two or more spaces are close or identical, then one or more of the following approaches can be used to determine the currently location of the user device 122.

In further implementations, the user device 122 determines which space it is currently located in using trilateration. Trilateration is the process of determining absolute or relative locations of points by measurement of distances using the geometry of circles, spheres or triangles. Generally speaking, trilateration involves viewing each terminal device as the center of a circle (two-dimensional trilateration) or a sphere (three-dimensional trilateration). The distance (calculated from the RSSI value) between the user device and each terminal device is the radius of the respective circle or sphere. Assuming there are at least three terminal devices in range of the user device, trilateration can be used to determine what space the user device is in based on the location of the intersection of the circles (or spheres). If the location of the intersection falls in a physical area associated with a space (e.g., space 104), then the terminal device is located in that space. The physical areas that make up a space are charted when terminal devices are assigned to spaces during configuration of the terminal devices (see FIG. 5). In further implementations, terminal devices themselves can determine their location relative to other terminal devices using trilateration based on the RSSI values for the other terminal devices.

In yet further implementations, the user device 122 determines which space it is currently located in using a combination of the above approaches.

Once the current space of the user device 122 is determined, the user device 122 can, in some implementations, present the GUI that shows equipment coupled to terminal devices in the current space. In further implementations, the GUI can show equipment associated with terminal devices that may be out-of-range of the user device 122. A command packet (or other type of packet) sent from the user device 122 will not directly reach an out-of-range terminal device. In some implementations, this limitation is overcome by a mesh network created by the terminal devices that can forward or relay packets.

To create the mesh network, each terminal device listens for advertisement broadcast packets from other terminal devices and creates a routing table populated with information about each terminal device from which it received an advertisement broadcast packet. For example, an entry in the routing table can comprise the terminal device identifier and the network identifier of the terminal device that broadcast the advertisement packet. A given terminal device can send its routing table to each terminal device in its routing table. Likewise, the given terminal device can receive routing tables from other terminal devices. When a routing table is received by the given terminal device, the routes in the received routing table are added to the given terminal device's own routing table. Each entry in the routing table can be expanded to include the identifier of a terminal device through which a “destination” terminal device is reachable if the destination terminal device is not directly reachable from the given terminal device. The mesh network comprises a set of terminal devices that are each reachable directly or indirectly from any of the terminal devices in the set.

If a “source” terminal device needs to send a packet to a “destination” terminal device, the source terminal device first checks its routing table to determine whether it can do so directly. If so, the source terminal device can transmit the packet to the destination terminal device directly. Otherwise, the source terminal device obtains from the routing table the identifier of an intermediate terminal device through which it can reach the destination terminal device and then sends the packet to the intermediate terminal device. The packet will travel from terminal device to terminal device until it reaches the destination terminal device. Other ways of creating and implementing mesh networks are possible.

Returning to FIG. 1, terminal devices 106, 116 and 118 have formed a mesh network (indicated by stars) and terminal devices 108, 110, 112, 114 and 120 have formed another mesh network (indicated by triangles). If the user device 122 located in space 102 wants to send a command packet to the out-of-range terminal device 120 in space 104, the user device 122 can do so by broadcasting the command packet to terminal devices in range or by sending the command packet to one or more selected terminal devices that are in range. A terminal device that receives a command packet that is destined for a different terminal device (based on the destination terminal device identifier in the command packet) can forward the packet according to the scheme above, for example. By way of illustration, in order to have a command packet delivered to out-of-range terminal device 120, the user device can send the packet to terminal device 108, 110, 112 or 114. If the packet is sent to terminal device 114, or if terminal device 114 receives the packet from another terminal device, terminal device 114 will forward the packet to terminal device 120 which will process the packet and implement the command.

FIG. 2 illustrates example communication of a user device 122 with terminal devices in two example spaces after the user device has roamed from space 102 to space 104. The user device 122 can periodically or at other times determine its current location in order to determine whether the user device 122 is in a new location. In this example, the user device 122 receives advertisement packets from terminal device 112 in space 102 and terminal devices 114, 116 and 120 in space 104. The user device 122 uses RSSI measurements of the terminal devices, as described above, to determine that it is currently located in space 104.

When the user device determines that it is in a new location, the GUI can be changed to show equipment coupled to terminal devices in the current space (e.g., the bedroom). In this example, the GUI of user device 122 shows the current state of the window 116 a (the window is open), the current state of the lamp (off) and the current state of the stereo (on). In some implementations, when a user device leaves a space the equipment in the space is disabled or put into an energy saving mode.

FIG. 4A illustrates components of an example terminal device 400. The terminal device 400 can be integrated into the smart plug 300, a wall outlet, a light switch, or other devices having alternating current (AC) or direct current (DC) powered circuits, for example. The terminal device 400 can contain fewer or more components than those illustrated in FIG. 4A. The terminal device 400 receives AC power input (e.g., from a wall socket) and provides the input to a DC power supply 404 which, in some implementations, is a switched-mode power supply (SMPS). The DC power supply 404 incorporates a switching regulator to convert electrical power while converting voltage and current characteristics.

The output of the DC power supply 404 powers the System on a Chip (SoC) 410 which, in some implementations, comprises a microcontroller 410 c, a memory 410 b, and a radio transceiver 410 a. The radio transceiver 410 a is configured to send and receive data using the antenna 406. The radio transceiver 410 a in some implementations operates at 2.4 GHz and supports the Bluetooth® low energy wireless protocol (e.g., Bluetooth® 4.0). Other frequencies (e.g., 3.6 GHz, 5 GHz, 60 GHz, etc.) and protocols (e.g., IEEE 802.11, IEEE 802.16, etc.) are possible. In further implementations, there can be more than one radio transceiver each utilizing the same or different frequency/protocol combinations. The microcontroller 410 c can be a 32-bit ARM® Cortex CPU, for example. Other microcontrollers are possible. The memory 410 b can include, for instance, Random Access Memory (RAM) and non-volatile Flash memory.

The hybrid AC switching circuit 412 comprises a triode for alternating current (TRIAC) 412 a and a relay 412 b which is an electrically operated switch controlled by the SoC 410. The TRIAC/Relay 412 controls the power output 424 which, in some implementations, powers the piece of equipment that is physically coupled to the terminal device (e.g., coupled to power receptacle 304 of smart plug 300). In further implementations, the power output 424 can be DC instead of AC and can be used to power equipment that require low voltages such as thermostats, for example. The relay 412 b can also be used to drive a motor. For example, the terminal device 400 can be integrated into devices such as motorized window shade controllers and garage door openers. The energy metering Integrated Circuit (IC) 420 monitors current energy output to the equipment. Instructions executing on the microcontroller 410 c can obtain energy consumption information from the energy metering IC 420 over time and store the information in the memory 410 b for future reference.

In some implementations, the terminal device 400 is wirelessly coupled to a piece of equipment through the transceiver 410 a. That is, the terminal device 400 using the transceiver 410 a can communicate with a piece of equipment that is able to communicate wirelessly such as, for example, a wireless network enabled thermostat or a wireless network hub. In these implementations, the TRIAC/relay 412 and the energy metering IC 420 can be omitted from the terminal device 400 or be disabled.

The terminal device 400 can include one or more sensors and one or more user interface devices. For example, the terminal device 400 can include an ambient light sensor 422 that provides measurements of ambient light to the SoC 401. Instructions executed by the microcontroller 410 c can use the ambient light measurement to direct the TRIAC 412 a to change the power delivered to the equipment (e.g., a lamp) to adjust the light output of the lamp to compensate for the ambient light. Other sensors are possible. Additional example sensors are discussed further below in reference to FIG. 4B.

The user interface devices can include, for example, one or more light emitting diodes (LEDs) 414, one or more tactile buttons 416 (e.g., button 306 on smart plug 300), and a touch-sensitive display 418. For example, if terminal device 400 is integrated into a light switch, the light switch could be controlled by use of the touchscreen instead of the usual tactile toggle switch. Other user interface devices are possible.

FIG. 4B illustrates components of another example terminal device 450. The terminal device 450 can be used for monitoring objects or an environment. The terminal device 450 can be implemented as a separate device or can be integrated into another device (e.g., a thermostat). The terminal device 450 can contain fewer or more components than those illustrated in FIG. 4B. The terminal device 450 receives power input 454 (AC or DC) from a battery or other source such as an AC power input (e.g., from a wall socket). If the power input is AC, the power is converted to DC.

The DC output of the power source 454 powers the SoC 410 which, in some implementations, comprises a microcontroller 410 c, a memory 410 b, and a radio transceiver 410 a. (See FIG. 4A.) The DC output of the power source 454 also powers one or more optional sensors 452. The sensors 452 provide input to the SoC 410. Instructions executed by the microcontroller 410 c can utilize input received from the sensors and perform various functions in response. The indication LEDs 414, tactile button 416 and ambient light sensor were described above in regards to FIG. 4A. The sensors can receive input from sources external to the terminal device 450 through one or more sensor inputs 460.

The magnetometer 452 a measures the strength and, in some implementations, the direction of magnetic fields. The magnetometer 452 a can be used to sense whether windows or doors, for example, are open or closed when the magnetometer 452 a's sensor input 460 is connected to a magnet that is attached to the window or door, for example. The accelerometer 452 i measures proper acceleration and can be used in conjunction with the magnetometer 452 a (as a compass) to detect three-dimensional movement. The humidity sensor 452 b, temperature sensor 452 c, and barometer 452 d measure ambient humidity, temperature, and air pressure, respectively.

Motion sensor 452 h detects motion in the environment surrounding the terminal device. The occupancy sensor 452 e can include an infrared sensor and a proximity sensor to determine if there are people present in a space. The carbon monoxide/carbon dioxide sensor 452 f can detect the presence of CO or CO₂ in the air, and the smoke sensor 452 g can detect the presence of smoke in the air. Air can be sampled by the sensors through an air intake input 460, for example. One or more of these sensors can be incorporated into the terminal device 400.

FIG. 5 illustrates an example initialization of a terminal device. To initialize a terminal device (e.g., terminal device 114), a user connects the terminal device to a power source such as a power socket and waits for their user device (e.g., user device 122) to receive an advertisement packet 502 from the terminal device. As discussed above, a terminal device makes its presence known to a user device by wirelessly broadcasting an advertisement packet 502 at various times or when prompted by a broadcast message sent by the user device. In some implementations, and as describe above, the advertisement packet 502 contains the transmit power of the terminal device, a terminal device identifier, status information, and a network identifier. The advertisement packet in some implementations is 27 bytes in length and the network identifier comprises 32 bits of a 128 bit field. If the terminal device has not been initialized, the network identifier is set to a predefined value (e.g., 0x00000000). Otherwise, the network identifier is set to the current value of the network identifier assigned to the terminal device. In some implementations, once a network identifier has been assigned to a terminal device, the terminal device can only be controlled by user devices which have permission to use the network identifier In further implementations, communication between the user device and the terminal device can be encrypted such that only the terminal device and the user device can decrypt messages sent between them.

Once the user device receives the advertisement packet 502 from the terminal device, the user device sends a connection request packet 504 to the user device. The destination address of the connection request packet 504 is the terminal device identifier obtained from the advertisement packet. The terminal device accepts the connection request packet 504 and sends a connection acknowledgement packet 506 to the user device in response. At this point, the user device and the terminal device are connected to each other.

After the connection is established, the user device provides an initialization packet to the terminal device which contains a network identifier and, optionally, one or more optional configuration parameters. The network identifier is determined by the user device and can be unique to the user of the user device. In some implementations, each terminal device initialized by the same user will be assigned the same network identifier. In further implementations, each network identifier is associated with a user account and a password. In order to access terminal devices having a given network identifier, the user associated with the network identifier must be logged into their account. This prevents other users from changing the configuration of terminal devices once they have been initialized by a particular user.

The optional configuration parameters can include a user specified name for the equipment coupled to the terminal device (e.g., “Bedside Lamp”), the equipment type (e.g., dimmable or non-dimmable light, television, appliance), and the name of the space which the terminal device is in (e.g., “Bedroom”). Alternatively, the configuration parameters could be stored on the user device instead of the transmitting them to the terminal device. Once the terminal device receives the initialization packet 508, the terminal device sets its network identifier to be the same as the network identifier (e.g., 0xFFFFFFFF) in the initialization packet. If there are any configuration parameters in the initialization packet, the terminal devices stores these values as well. After initialization, the terminal device will advertise its newly assigned network identifier (e.g., 0xFFFFFFFF) in the advertisement packet 510.

In some implementations, when initializing a terminal device, the user is required to stand a predetermined distance (e.g., 15 feet) from the terminal device so that the user device can obtain a RSSI measurement of the terminal device for future reference. The transmit power of all terminal devices can be set to the same value when the terminal devices are initialized in order to make the RSSI measurement consistent for all terminal devices. The user device associates the RSSI measurements for all terminal devices assigned to a given space with the name of the space. The distance computation for each RSSI measurement for terminal devices assigned to a particular space is a radius of a circle in which the respective terminal device is the center. The areas of the circles/spheres comprise the physical areas that make up the particular space in some implementations. These “charted” areas are used during trilateration to determine the current space of a user device.

The following example GUIs illustrated in FIGS. 6A-E can be presented on a display of the user device (e.g., user device 122) or on anther device such as, for example, a personal computer, a tablet computer, or a laptop computer.

FIG. 6A illustrates example GUIs for configuring a terminal device. GUI 601 allows the user to select one of the terminal devices (terminal device 601 a or terminal device 601 b) to configure by touching the name of the terminal device (“Smartplug 1” or “Smartplug 2”) with a finger or by speaking a command, for example. The terminal devices are terminal devices that the user device has received advertisement packets from, for example.

The selected terminal device's configuration is then presented in GUI 602. The GUI 602 allows a user to assign an icon 602 c representative of the equipment type coupled to the terminal device. The GUI 602 also allows the user to assign an equipment type to the equipment if there is not already an equipment type assigned. In some implementations, selecting the icon 602 c from a gallery of predefined icons, for example, also selects the equipment type. The configuration shown in GUI 602 is particular to the equipment type. Examples of types of equipment are lamps, motorized shades/curtains, televisions, heaters, appliances, stereo components, and so on. In this example, the equipment type is a lamp. The configuration for a simple lamp is a Boolean value indicating whether or not the lamp is dimmable 602 b. The user can also assign a name to the equipment by typing or speaking the name in text input field 602 a. (The user-specified lamp name in this example is “Lampy” as shown in GUI 603.) The user device can transmit the equipment configuration as well as a network identifier in an initialization packet 508 to the selected terminal device. The terminal device receives the configuration information and adjusts its settings accordingly. Once a terminal device is configured, the terminal device appears in the GUI as the user-provided equipment name or icon instead of as the name of a terminal device.

GUI 603 also allows the user to select a space to assign to the terminal device. The region 603 a of the GUI 603 displays available spaces: Living Room 603 b and Bedroom 603 c. The user can also select 603 d to create a new space. In this example, the user has assigned the Living Room 603 b space to the terminal device.

GUI 604 shows additional configuration parameters for the lamp including a timer setting 604 a and a proximity setting 604 b. The timer setting 604 a allows the user to set a schedule for when the lamp (or other equipment being configured) should be turned on and off by selecting buttons. For example, the user can set a weekday schedule and a weekend schedule. In some implementations, a so-called “vacation mode” time setting will cause the lamp to turn on and off at random times to give the appearance that someone is home. The proximity setting 604 b can be configured so that the lamp (or other equipment being configured) is automatically turned on when the user device enters the space (e.g., “Living Room”) or turns off when the user device enters the space. When the user device leaves the space, the lamp (or other equipment) returns to its prior configuration.

FIG. 6B illustrates example GUIs for configuring a space. GUI 605 allows a user to turn on all equipment in a space by selecting control 605 a. For example, a quick finger swipe (or other user input) over control 605 a will serve to turn on or off all equipment in all spaces. As shown in GUI 605, Lampy 605 b and Television 605 c are assigned to the Living Room space and The Other Lamp 605 d is assigned to the Bedroom space. Swiping or selecting an individual equipment name (e.g., television 605 c) will cause that equipment to be turned on or off (depending on the current state of the equipment).

GUI 606 allows control of a single space. A quick finger swipe (or other user input) over control 606 a will serve to turn on or off all equipment in the space. The user can add or remove equipment assigned to the space by selecting the edit button 606 d. The user can further configure a particular piece of equipment by selecting the equipment's icon (e.g., lamp icon 606 b or television icon 606 c). The configuration parameters for the selected piece of equipment appear in region 604 e. In some implementations, GUI 606 automatically changes to the space that the user device is currently located. For example, in FIG. 1 the user device 122 displays the Living Room space 102 configuration for GUI 606 but when the user device is moved into the Bedroom space 104, the GUI 606 automatically changes to display the Bedroom space 104 configuration. In yet further implementations, floor plan can be displayed along with the GUI 606 to indicate the actually physical locations of equipment in the space.

FIG. 6C illustrates example GUIs for configuring and activating profiles. Profiles are preset equipment settings for equipment in one or more spaces. A profile is assigned a name by a user. A profile can be activated or deactivated with a single user action, for example. In some implementations, once a profile is activated, the associated equipment settings override any current equipment settings (including timers in some implementations). In further implementations, when a profile is deactivated the prior settings of the equipment are restored.

GUI 607 is an example GUI for activating and deactivating profiles. The GUI 607 lists profiles that are already defined in area 607 a. In some implementations, the GUI 607 indicates which profile(s) are currently active (not shown). In this example, the user-defined profiles are “Movie”, “Vacation” and “Party”. A profile can be activated or deactivated by user selection of the profile name, for example. Additional profiles can be added by user selection of the button 607 b. GUI 608 is an example GUI for configuring a new or existing profile. In this example, the configuration is for a profile named “Movie”. Indicator 608 a designates whether the profile is currently active. The equipment controlled by the profile are listed in another region of the GUI 608. For instance, lamp 608 b, television 608 c, and lamp 608 d are controlled by the “Movie” profile. Selection of any of the icons (608 a, 608 c, 608 d) allows the user to edit the profile configuration for the corresponding equipment in region 608 f.

FIG. 6D illustrates example GUIs for exploring energy consumption. GUI 610 is an example GUI that illustrates energy consumption by different pieces of equipment. Pie chart 610 c illustrates the percentage of total energy consumed for a given time period by each piece of equipment. Pie chart 610 d (partially visible) illustrates the percentage of energy consumed by each space. User selection of button 610 b causes the information to be displayed in a line graph instead of a pie chart. User selection of button 610 a causes the information to be displayed in a pie chart. Other types of charts and graphs are possible. GUI 611 is an example GUI that illustrates energy consumption by different pieces of equipment in more detail by providing the numeric percentage consumed by each piece of equipment. Selection of a slice of the pie chart (e.g., slice 611 b) causes presentation of GUI 612 including a chart 612 c showing the energy consumption by the equipment “Lampy” 612 b.

FIG. 6E illustrates example GUIs for exploring energy cost. GUI 613 is an example GUI for illustrating the energy cost in dollars (or some other currency), for example, for each piece of equipment as a function of time. In this example, the chart shows energy cost in dollars for a television 613 a, a lamp 613 b, an appliance 613 c, and task light 613 d. User selectable controls 613 e-g allow user to view the chart in terms of cost 613 e, kilowatt hours (kWh) 613 f, or compare 613 g the energy usage to those of similar households. GUI 614 is an example GUI for illustrating energy cost on a per spaces basis. For example, the Living Room space is illustrated by line 614 a and the Bedroom space is illustrated by line 614 b. As with GUI 613, user selectable controls 613 e-g allow the user to view the chart in terms of cost 613 e, kilowatt hours (kWh) 613 f, or compare 613 g the energy usage to those of similar households. GUI 615 is an example GUI that illustrates overall energy cost or kilowatt hours (kWh), of all pieces of equipment as shown in chart 615 a. GUI 616 is an example GUI which allows a user to select a portion of the graph 616 a (e.g., with a finger touch) to see detailed information 616 b regarding the selected portion of the graph. In this example, the detailed information 616 b indicates that the overall energy cost on February 21 was $4.16.

FIG. 7 is a block diagram illustrating an example system 700 for monitoring and control of equipment on which the techniques described herein can be implemented. The system 700 includes one or more user devices 706, one or more terminal devices 704, and a server system 702.

Each user device 706 includes a communication module 706 a, a learning module 706 b, an energy usage module 706 c, an energy saver module 706 d, a sensor module 706 e, a user activity module 706 f, a GUI module 706 g, a profile module 706 h, a current location module 706 i, storage for user profiles 706 j, storage for equipment configurations 706 k, storage for information about spaces 706 l, and storage for equipment energy histories 706 m. The modules 706 a-i can be implemented as software, hardware or a combination of software and hardware that is executed on the user device. Fewer or more modules are possible. The storage 706 j-m can be implemented as random access memory, Flash memory, or other types of persistent or non-persistent storage.

Each terminal device 704 includes a communication module 704 a, a monitor module 704 b, a control module 704 c, storage for energy history 704 d, storage for the terminal device's equipment configuration settings 704 e, and storage for an equipment schedule 704 f. The modules 704 a-c can be implemented as software, hardware or a combination of software and hardware that is executed on the terminal device. Fewer or more modules are possible. The storage 706 d-f can be implemented as Flash memory, read-only memory, or other types of persistent storage.

The server system 702 includes a communication module 702 a, a data replicator module 702 b, a comparison module 702 c, an application directory module 702 d, and storage for user data 702 f. The modules 702 a-d can be implemented as software, hardware or a combination of software and hardware that is executed on one or more data processing apparatus located in one or more geographic locations. Fewer or more modules are possible. The storage 702 f can be implemented as random access memory, Flash memory, network accessible storage such as hard drives, or other types of persistent storage.

Network 708 can include a large computer network, examples of which include a local area network (LAN), wide area network (WAN), the Internet, a cellular network, or a combination thereof connecting a number of mobile computing devices, fixed computing devices, and server systems. The network(s) included in network 708 can provide for communications under various modes or protocols, examples of which include Transmission Control Protocol/Internet Protocol (TCP/IP), Global System for Mobile communication (GSM) voice calls, Short Electronic message Service (SMS), Enhanced Messaging Service (EMS), or Multimedia Messaging Service (MMS) messaging, Ethernet, Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Personal Digital Cellular (PDC), Wideband Code Division Multiple Access (WCDMA), CDMA2000, or General Packet Radio System (GPRS), among others. Communication can occur through a radio-frequency transceiver. In addition, short-range communication can occur, e.g., using a Bluetooth®, WiFi, or other such transceiver system.

The communication module 706 a in the user device 706 can communicate wirelessly with one or more terminal devices (e.g., terminal device 704) using Bluetooth®, WiFi, or another wireless-protocol. The communication module 706 a of the user device 706 receives an advertisement packet 502 transmitted by the communication module 704 a of the terminal device 704. The communication module 706 a can respond with a connection request 504 which is received by the terminal device 704's communication module 704 a. In response, the communication module 704 a transmits a connection acknowledgment 506 to the user device 706 indicating that a connection between the terminal device 704 and the user device 706 has been established.

Once a connection between the terminal device 704 and the user device 706 has been established by the respective communication modules, the user device 706 can transmit a command packet or an initialization packet 508 to the terminal device 704. Regarding the former, the command packet contains one or more equipment commands for the terminal device 704 to implement immediately, such as turning equipment coupled to the terminal device on or off The commands can be implemented by the communication module 704 a or the control module 704 c, for example.

Configuration information for the terminal device 704 is stored in the equipment configurations 706 k storage of the user device 706 by the GUI module 706 g as part of the equipment configuration, for example (see FIG. 6A). The communication module 706 a retrieves the stored configuration information and transmits it as configuration parameters in an initialization packet 508 to the terminal device 704. The terminal device 704's communication module 704 a receives the initialization packet 508 and provides the network identifier and configuration parameters from the initialization packet 508 to the control module 704 c. The control module 704 c stores the network identifier and the configuration parameters in the equipment configuration settings 704 e and then controls the equipment according to the received configuration parameters. The configuration parameters can specify, for example, the equipment type, whether the equipment is dimmable 602 b (if the equipment is a light), an optional proximity configuration 604 b, and an optional timer configuration 604 a. The timer configuration is stored as a schedule for the equipment in the equipment schedule storage 704 f If a timer configuration is provided, the control module 704 c will turn the equipment on and off according to the schedule.

The monitor module 704 b of the terminal device 704 collects information regarding the equipment's energy usage over time and stores the information in the energy history storage 704 d. For example, energy usage in terms of kilowatt hours (kWh) per hour per day for the last four months can be stored in the energy history storage 704 d. The user device 706′s energy usage module 706 c can request the energy usage information from the terminal device 704 by causing the communication module 706 a to transmit an energy history request packet to the user device 704. The communication module 704 a of the terminal device 704 receives the energy history request packet from the user device 706 and, in response, causes the monitor module 704 b to retrieve the energy history information from the storage 704 d. The monitor module 704 b then causes the communication module 704 a to transmit the energy history information to the user device 706. The communication module 706 a of the user device 706 receives the energy history information from the terminal device 704 and provides it to the energy usage module 706 c. The energy usage module 706 c stores the received energy history information in the storage for equipment energy histories 706 m. The storage for equipment energy histories 706 m is used by the GUI module 706 g to display energy history information (see FIGS. 6D-6E).

The current location module 706 i determines the current location of the user device 706 and takes appropriate action, if necessary, when a change in location is detected. The communication module 706 a obtains RSSI values for terminal devices that it receives advertisement packets from. The communication module 706 a provides the RSSI values to the current location module 706 i which determines the current location as described above in regards to FIG. 1. When the current location of the user device 706 has changed to a new space, the current location module 706 i signals the communication module 706 a to transmit a packet announcing the presence of the user device 706 to terminal devices in the new space. In various implementations, the packet contains an identifier of the respective user device and the name of the new space. The terminal device communication modules 704 a receive the packets and, in some implementations, save their respective equipment configurations in anticipation that the user device 706 will change the settings.

The current location module 706 i determines what pieces of equipment are assigned to the new space. The configuration(s) of the equipment assigned to the new space are gathered from the configuration storage 706 k and scanned to determine if any of the pieces of equipment has a proximity setting enabled (e.g., proximity setting 604 b). If so, command packets are sent to the terminal devices coupled to those pieces of equipment to turn the equipment on or off according to the proximity settings. In further implementations, the current location module 706 i signals the GUI module 706 g to display the new space (e.g., in GUI 606).

In various implementations, when a user device 706 leaves a space (and enters a new space), the current location module 706 i signals the communication module 706 a to transmit a packet announcing the presence of the user device 706 to terminal devices in the new space. Terminal devices in the prior space that receive the packet can restore their saved equipment configurations if the configurations had been changed by the user device so that whatever state the space was in before the user device 706 entered is reinstated. If a particular terminal device in the prior space does not receive the packet, another terminal device that does receive it can forward the packet to the particular terminal device using the mesh network which was described above. Alternatively, or in addition to this, the communication module 704 a of the terminal devices can be configured to periodically poll a user device 706 to see if the user device 706 is still in the space. If the user device 706 is unreachable or responds in the negative, then the terminal devices can restore their saved equipment configurations.

If a user device (user device ‘B’) has changed location to a new space and but there is already another user device (user device ‘A’) in the new space, one of the user devices will take priority over the other. In some implementations, the packet that announces to the terminal devices when a user device has newly entered the space contains priority information. If the priority information of user device B does not trump the priority information of user device A, then the terminal devices will ignore any command packets that user device B may transmit to the terminal devices. Otherwise, the terminal devices will save their respective equipment configurations in anticipation that user device B will change their equipment configurations. Priority among users can be established in a number of ways. If user A is a parent and user B is a child, for instance, then a rule can be established that the user device of a parent always has higher priority than that of a child. Or the user device that enters a space first has priority over other user devices that enter the space afterwards. Other types of rules are possible.

he user activity module 706 f monitors user activities and, in some implementations, can perform one or more actions in response to detecting an activity of a user. An activity is, for example, watching a movie, playing an electronic game, activating a media controller, opening or closing a window or a door, adjusting a thermostat, turning an oven on or off, turning a fan on or off, or entering a bedroom after a particular time. Other types of activities are possible. The user activity module 706 f of the user device 706 is made aware of a user activity through an activity update message that is received by the communication module 706 a and delivered to the user activity module 706 f. The activity update message indicates the type of activity the user is engaged in. The activity update message is generated in some implementations by an application programming interface (API) on the device (e.g., a set-top box, a wireless thermostat, and so on) that detects the user activity. Received activity update messages can cause the user activity module 706 f to perform an action such as, for instance, sending a message to the user (e.g., “the living room window is open and rain is predicted) or sending a command packet to one or more pieces of equipment to, for example, dim the lights when the user activity is watching a movie, lower motorized blinds, or raise the indoor temperature. Actions can be defined programmatically through the API or interactively through use of a graphical user interface presented on the user device, for example. In some implementations, software applications that support the activity update API are registered in the server system 702's application directory 702 d. The application directory 702 d allows users to download the applications onto their user devices for adding activity-based functionality to the user device 706.

The learning module 706 b tracks equipment usage patterns and activity patterns over time for one or more users. Tracking information for equipment usage comprises tuples of the following information: <user, time, terminal device, command>, where user identifiers the user, time indicates the time at which the command was sent by the user device of the user to the identified terminal device. Tracking information for activities comprises tuples of the following information: <user, time, activity, space>, where user identifies the user, time indicates the time at which the user commenced the activity identified by activity, and space identifies the space in which the activity was commenced. The user device 706 can store the tracked information locally or in the server system 702.

The learning module 706 b can be derive patterns from the tracking information and use the patterns to automatically create timer settings (e.g., timer setting 604 a) for equipment and define actions for the user activity module 706 f. Patterns of equipment usage are derived for a given user by detecting that the user, at a given time of day or time range, causes a user device to transmit a particular command to a particular terminal device. For example, given the equipment usage tracking information:

<David, 5:00 PM Jan. 14, 2013, living room lamp, turn on>

<David, 5:16 PM Jan. 15, 2013, living room lamp, turn on>

<David, 4:50 PM Jan. 16, 2013, living room lamp, turn on>

<David, 5:05 PM Jan. 17, 2013, living room lamp, turn on>

a pattern for user David can be deduced that specifies turning on the living room lamp each weekday at around 5:00 PM in the evening. A timer setting for the living room lamp can be created and stored as a schedule in the equipment schedule storage 704 f. The control module 704 c will turn the equipment on and off according to the schedule.

Patterns of activities are derived for a given user by detecting that the user device of the user, at a given time of day or time range, receives an activity update message. For example, given the equipment usage tracking information:

<Susan, 8:00 PM Jan. 14, 2013, play movie, bedroom>

<Susan, 8:22 PM Jan. 15, 2013, play movie, bedroom >

<Susan, 8:15 PM Jan. 17, 2013, play movie, bedroom >

a pattern for user Susan can be deduced that specifies playing a movie in the bedroom each weekday at around 8:20 PM in the evening. An action can be automatically defined to dim lights in the bedroom at 8:20 PM each weekday.

The energy saver module 706 d tracks occupancy patterns and energy usage patterns over time for one or more users. Tracking information for occupancy comprises tuples of the following information: <user, entry time, exit time, space>, where user identifiers the user, entry time is the time at which the user device of the user entered the space identified by space, and exit time is the time at which the user device of the user exited the space. The occupancy tracking information can be obtained from the current location module 706 i, for example. Energy usage information comprises tuples of the following information: <on time, off time, terminal device, energy usage>, where on time is the time when equipment coupled to the terminal device identified by terminal device was turned on, off time is the time when equipment coupled to the terminal device was turned off, and energy usage indicates the amount of energy (e.g., kWh) consumed by the equipment during the time period between on time and off time. The energy usage information can be obtained from the energy usage module 706 c, for example.

The energy saver module 706 d can be derive occupancy and energy usage patterns from the tracking information. For example, after analyzing the occupancy tuples for a given user, the energy saver module 706 d determines that user David is located in the bedroom space on average from 9:30 PM-6:30 AM weekdays, and is located in the living room space from 6:45 PM-9:20 PM weekdays. Other times David is not present in any of the spaces. The energy saver module 706 d can analyze the energy usage tuples to determine times when equipment is consuming power and the amount of power consumed. By way of illustration, a lamp in the bedroom space consumes power from 6:45 PM-10:00 PM weekdays, even though user David occupies the living room for the majority of this time. The energy saver module 706 d can compare occupancy patterns for a given user or users with energy usage patterns for one or more pieces of equipment to identify times when equipment is consuming power in unoccupied spaces. The energy saver module 706 d can notify a user through the GUI module 706 g to suggest turning off equipment in unoccupied spaces to save energy.

Additionally, the energy saver module 706 d can compare activity patterns to energy consumption to suggest turning off equipment that is not needed for the given activity. Other types of comparisons are possible such as, for example, comparing the energy use of equipment in a home to similar homes in the same geographic area to suggest ways to save energy. The energy saver module 706 d can compare the energy usage of one user to another for the same spaces and make suggestions to the user that consumes the most power regarding how that user could alter their use of equipment to correspond to that of the other user to reduce their power consumption.

The sensor module 706 e obtains measurements from various physical sensors integrated into the user device and modifies configurations of one or more pieces of equipment based on the obtained measurements. By way of example, a sensor measurement is a measurement of motion from a motion detector sensor, a measure of ambient light from an ambient light sensor, a measurement of sound from a microphone, a measurement of ambient temperature from a thermometer, a measurement of physical location from a global positioning system, a measurement of touch from a touch-sensitive display device, a measurement of compass direction from a compass, a measurement of direction or intensity of a magnetic field from a magnetometer, a measurement of humidity from a humidity sensor, a measurement of atmospheric pressure from a barometer, a measurement of luminance from a light sensor, a measurement of orientation from an orientation sensor, or a measurement of proximity from a proximity sensor. Other measurements and sensors are possible.

The sensor module 706 e obtains one or more sensor measurements and, if the sensor measurements match a predefined pattern, formulates a command for the communication module 706 a to send to a terminal device in the current space (as determined by the current location module 706 i) based on the measurements. As an example, the pattern can be a measurement of motion that indicates a substantially n upward or downward motion of the user device. (Instead of motion, the pattern can be a measurement of orientation that indicates vertical or horizontal orientation of the user device.) The upward or downward motion can trigger formulation of a command for a lamp or a speaker, for instance, to increase the brightness/sound volume or decrease the brightness/sound volume, respectively, of the lamp or speaker. The pattern can also be a measurement of sound that indicates a first sound followed by a second sound, where the second sound occurs within 5 seconds (or some other interval) after the first sound. The pattern can trigger formulation of a command for a lamp or other piece of equipment to turn on or turn off the piece of equipment. Other patterns are possible.

A measurement of ambient light can cause formulation of a command to raise or lower the brightness of a lamp or other piece of equipment to account for the ambient light. A measurement of ambient sound can cause formulation of a command to raise or lower the volume of a television or other piece of equipment to account for the ambient sound. A measurement of ambient temperature or humidity can cause formulation of a command to raise or lower the temperature of a thermostat, heater, fan, or other piece of equipment to account for the ambient temperature or humidity.

The profile module 706 h manages profiles for users of the user device 706. Each user can have their own profiles. As described above in reference to FIG. 6C, profiles are present equipment settings for equipment in one or more spaces. When a user creates a profile (e.g., through user interaction with GUI 607 and GUI 608), the equipment settings for the profile are provided by the GUI module 706 g to the profile module 706 h. The profile module 706 h associates the profile with the user and stores the profile in the profile storage 706 j. Likewise, when a user edits a profile (e.g., through user interaction with GUI 607 and GUI 608), any changes to the equipment settings for the profile are provided by the GUI module 706 g to the profile module 706 h. The profile module 706 h updates the profile in the profile storage 706 j with the changed settings.

When a profile is activated (e.g., through user interaction with GUI 607), the GUI module 706 g requests the profile from the profile module 706 h and, in turn, the profile module 706 h retrieves the profile from profile storage 706 j and provides it to the GUI module 706 g. The GUI module 706 g converts the profile to one or more commands to change settings on one or more pieces of equipment and provides the commands to the communication module 706 a. The communication module 706 a transmits the commands to terminal devices for the equipment and thus activates the profile.

In addition, the GUI module 706 g allows users to add equipment (e.g., through user interaction with GUIs 601 and 602) and modify settings of the equipment (e.g., through user interaction with GUI 604). The GUI module 706 g stores the settings in configuration storage 706 k and, when the user wishes to edit the settings for a piece of equipment, retrieves the settings from configuration storage 706 k. When settings for a piece of equipment are changed, the GUI module 706 g converts the settings to one or more commands to change the settings on the piece of equipment and provides the commands to the communication module 706 a. The communication module 706 a transmits the commands to the terminal device for the piece of equipment.

The GUI module 706 g allows users to define spaces and activate or deactivate all of the equipment in a space (e.g., through user interaction with GUIs 605-606). A space definition comprises a name and the identity of one or more terminal devices in the space. The GUI module 706 g stores new space definitions in spaces storage 706 l. When a user wishes to turn on or turn off all equipment in a space (e.g., through interaction with GUI 606), the GUI module 706 g generates one or more commands to send to the equipment in the space and invokes the communication module 706 a to transmit the commands to the relevant terminal devices.

Finally, in addition to allowing users to create, edit and activate profiles, the GUI module 706 g presents energy consumption information (e.g., in GUIs 610-616) culled from the energy history storage 706 m.

Some implementations include a server system 702. The server system 702 provides data replication and other services to terminal devices and user devices. The communication module 702 a of the server system 702 can communicate wirelessly with one or more terminal devices (e.g., terminal device 704) and user devices (e.g., user device 706) using Bluetooth®, WiFi, or another wireless-protocol. The data replicator module 702 b of the server system replicates data stored on terminal devices (e.g., terminal device 704), user devices (e.g., user device 706), or both. For example, the data replicator receives energy history data (e.g., energy history data 704 d or 706 m) from the communication module 702 a, associates the data with a given user, and stores the data in user storage 702 f.

The energy history data can be “pulled” by the data replicator 702 b, that is, the data replicator 702 b can use the communication module 702 a to send requests for the data to the terminal devices and/or user devices. Alternatively, the energy history data can be “pushed” to the server system 702 by the terminal devices and/or the user devices by the respective communication modules of the devices. For example, at various times the communication module 706 a of the user device 706 can send updated energy history data to the server system 702 without prompting from the server system 702. Likewise, profiles in profile storage 706 b, equipment settings in configuration storage 706 k, and space definitions in space definition storage 706 l can be pulled from the server system 702 or pushed to the server system 702. Having this information replicated in the server system 702 allows the information to be accessed and modified from different terminal and user devices as well as other data processing apparatus. A comparison module 702 c can compare energy usage for a given user with the energy use of users in similar dwellings and provide the comparison to the user by sending a message using the communication module 702 a to the user device of the user. The message can be presented to the user by the GUI module 706 g, for example.

An application directory module 702 d provides software applications for download to user devices for adding activity-based functionality to the user devices. The software applications are programmed to send activity update messages using the API described above in regards to the user activity module 706 f. Once downloaded, the programs can define actions on the user device The application directory 702 d allows users to download the applications onto their user devices.

FIG. 8 is a flow chart of an example process 800 for changing a GUI to reflect the current location of a user device. The process 800 can be implemented, for example, by the current location module 706 i, the GUI module 706 g, and the communication module 706 a in the user device 706 of FIG. 7. A user device wireless communicates with one or more terminal devices that are in range of the user device to obtain information from the terminal devices (e.g., communication module 706 a; 802). Each of the terminal devices (e.g., terminal device 704) is configured to monitor a respective piece of equipment associated with the terminal device. The obtained information is used (e.g., by the current location module 706 i) to determine that the user device is located in a first space of a physical structure (804). Responsive to determining that the user device is located in the first space, a graphical representation (e.g., GUI 606) of one or more pieces of equipment that are physically located in the first space is presented on the user device (e.g., by the GUI module 706 g; 806). Energy usage information is received (e.g., by the communication module 706 b) from one or more of the terminal devices (808). The received energy usage information is presented in the graphical representation (e.g., GUI 612; 810).

The process 900 can be implemented, for example, by the current location module 706 i, the learning module 706 b, and the energy saver module 706 d of the user device 706 of FIG. 7. Different respective spaces occupied by users at different times are identified (902). The spaces can be identified by, for example, the current location module 706 i. From this information, occupancy patterns for the users can be determined by, for example, the energy saving module 706 d. Times at which the user device of each user sends one or more commands to one or more pieces of equipment in one or more of the spaces occupied by the user are determined (904). The times can be determined by, for example, the learning module 706 b. A schedule of equipment settings is derived for each user based on the times at which the user device of the user sends commands to the pieces of equipment (906). The schedules can be determined by, for example, the learning module 706 b. For a given user, the current space of the user is determined by the user device (e.g., current location module 706 i) and based on the determination and the current time, one or more pieces of equipment are configured in the space according to the user's schedule (908).

FIG. 10 is a flow chart of an example process 1000 for configuring terminal devices when more than one user device is in a space. The process 1000 can be implemented, for example, by the current location module 706 i of the user device 706 of FIG. 7 or by the control module 704 c of the terminal device 704. A first user and a second user are both detected as being present in a particular space of a physical structure (1002). The space comprises one or more terminal devices each being coupled to a respective piece of equipment and having a respective configuration. One of the users is selected where the selected user entered the particular space before the other user (1004). One or more configurations associated with the selected user are obtained, wherein each of the second configurations specifies respective configuration parameters for one of the pieces equipment (1006). Wirelessly communicating each obtained configuration to a different terminal device wherein the terminal device is configured to receive the obtained configuration wirelessly from the user device and configure the piece of equipment coupled to the terminal device with the second configuration (1008).

The process 1100 can be implemented, for example, by the current location module 706 i, the user activity module 706 f, and the communication module 706 a in the user device 706 of FIG. 7. A user device is determined to be located in a first space of a plurality of spaces of a physical structure (e.g., the current location module 706 i; 1102). One or more respective configurations for a current user of the user device are obtained for one or more of pieces of equipment that are physically located in each of the one or more spaces, wherein each piece of equipment is associated with a respective terminal device that is configured to implement received configurations for the associated piece of equipment (1104). Information is received (e.g., by the user activity module 706 f) indicating a current activity of the user (1106). One or more of the respective configurations are modified based on, at least, the current activity of the user (e.g., the user activity module 706 f; 1108). The modified respective configurations are wirelessly communicated to one or more of the terminal devices (e.g., the communication module 706 a; 1110).

FIG. 12 is a flow chart of an example process 1200 for modifying equipment configurations based on user-device sensor measurements.
